20 Southern California rallied from a late 13-point deficit for a 28-27 victory over Arizona State on Saturday in the Pac-12's long-delayed season opener. Bru McCoy caught a deflected 26-yard TD pass with 2:52 left for the Trojans (1-0), and Max Williams recovered the onside kick. USC's defense then stopped Arizona State (0-1) on downs near midfield with 50 seconds left to preserve an astonishing comeback for perpetually embattled coach Clay Helton's team. New Arizona State co-defensive coordinator Marvin Lewis also was on the verge of a resilient debut before the Trojans broke through. “I don’t think we were out of gas,” Arizona State safety Evan Fields said.
